Same as Figure 5 but for the chemical composition of Ne2. Each scaling mass (magenta lines) corresponds to the WD mass (from right to left, 0.7–﹩1.35\,{M}_{\odot }﹩ by ﹩0.05\,{M}_{\odot }﹩ steps, except ﹩1.33\,{M}_{\odot }﹩), the same as those tabulated in Table 2 (Ne2). The thick magenta lines of equi-M_sc (or equi-M_WD) correspond to the WD mass region for neon novae (﹩{M}_{\mathrm{WD}}\geqslant 1.05\,{M}_{\odot }﹩).
